Coastal erosion is the loss or displacement of land, ... their tendency to cause erosion in adjacent beaches and dunes, and the unintended diversion of stormwater and ...
Tsunamis can cause significant erosion and sediment displacement. They can strip away years of accumulated sand from beaches and devastate coastal vegetation. These powerful waves can flood inland areas far beyond the typical high-tide mark.
Erosion and changes in the form of river banks may be measured by inserting metal rods into the bank and marking the position of the bank surface along the rods at different times. [23] Thermal erosion is the result of melting and weakening permafrost due to moving water. [24] It can occur both along rivers and at the coast.
Coastal sediment supply is the transport of sediment to the beach environment by both fluvial and aeolian transport. While aeolian transport plays a role in the overall sedimentary budget for the coastal environment, it is paled in comparison to the fluvial supply which makes up 95% of sediment entering the ocean.

Beach erosion is a specific subset of coastal erosion, which in turn is a type of bioerosion which alters coastal geography through beach morphodynamics. There are numerous incidences of the modern recession of beaches , mainly due to a gradient in longshore drift and coastal development hazards .
Sand is dumped on the beach to shore up the dune damaged by beach erosion on February 20, 2024 on Singer Island in Riviera Beach, Florida. Diamond Walker is a journalist at The Palm Beach Post ...
Storm surge at those levels is likely to cause flash flooding in areas including Cherry Grove in North Myrtle Beach, and the continued erosion of sand can leave nearby properties more vulnerable ...
Coastal erosion is one of the most significant hazards associated with the coast. Not in terms of a rare massive release of energy or material resulting in loss of life, as is associated with tsunami and cyclones, but in terms of a continual chronic release that forms a threat to infrastructure, capital assets and property.
